New Low Power SSD with Unmatched Security Designed for Defense and Industrial Markets; Offered in an Extremely Compact Form Factor

ALISO VIEJO, Calif., Aug. 13, 2015 — (PRNewswire) — Microsemi Corporation (Nasdaq:
MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today announced a compact form factor
serial advanced technology attachment (SATA) solid state drive (SSD) for industrial, defense, intelligence, unmanned aerial vehicles (
UAV) as well as secure laptops where ultimate security for data-at-rest is required. The low power mSATA SSD has 64GB single-level cell (SLC) flash capacity in a 50mm x 30mm compact form factor and is 65 percent smaller than similar 2.5" devices. The SSD also features Microsemi's Armor™ processor, which solves obsolescence issues common in industrial and defense applications by guaranteeing long-term security and performance.

"Microsemi's miniaturization technology coupled with high-end security features in the Armor processor enable customers to design secure systems and reduce the footprint otherwise required," said Bill Sorrentino, tactical marketing manager for Microsemi's Memory and Storage business. "In the advanced deep sleep low power mode, the SSD is only using 150mW and can be 'instant on.' This feature will enable longer field life for battery powered applications. In addition, it will cut down on cooling required for products where heat is a concern."

The device is Microsemi's newest addition to the advanced TRRUST-Stor® family of secure SSDs in a compact MO-300 mSATA form factor. This SSD includes security features such as hardware based AES-256 XTS encryption and advanced key management systems. The new Armor III processor also has the capability to sanitize the drive with the NSA 9-12 protocol in less than two minutes, which is up to three times faster than industry standard.

As part of the TRRUST-Stor best-in-class self-encrypting drive (SED) technology, the product offers security that is unmatched in a standard mSATA SSD. Advanced key management modes and isolated key fill capabilities protect unpowered data at rest by assuring that the encryption key does not reside in the SSD once power is removed. For sensitive applications, a hardware or software signal can trigger an erase of the encryption key in less than 30 milliseconds (ms). A second security layer can be activated to erase the entire storage media in less than 10 seconds, rendering data forensically unrecoverable.

"Microsemi's low power mSATA SLC-based SSD is specifically designed for embedded applications requiring the highest levels of security and reliability. Our mission is to help our customers solve the most demanding data reliability and protection challenges," said Charlie Leader, vice president and general manager for Microsemi's Power & Microelectronics Group. "As a leader in the design and delivery of specialized, secure storage systems, Microsemi will continue our commitment to providing the highest levels of performance while meeting the most stringent security requirements."
